Step-by-step explanation:

Answer:

Assuming the cones are the same height, then

V1 = pi * r^2 * h/3 = 3.14159*1^2*h/3

V2 = 3.14159*2.5^2*h/3 = 3.14159*6.25*h/3

V1/V2=(3.14159*h/3)/(3.14159*6.25)*h/3

V1/V2 = 1/6.25 = .16

V2/V1=(3.14159*6.25)*h/3/(3.14159*h/3)

V2/V1=6.25/1 = 6.25

Answer: 3 divided by 1/4 is the first and the second is number fourths un 3 :)

Step-by-step explanation:

3÷1/4 is the expression which can be used to represent the model

A fraction represents a part of a whole.

An expression is combination of variables, numbers and operators.

In the given model there are twelve blocks.

The 12 blocks are divided to three parts.

Each part has 4 blocks.

This can be represented by the expression 3÷1/4

Three divided by one by four is the required expression.

Hence, 3÷1/4 is the expression which can be used to represent the model

Answer:

y = - 143481.1924 + 10011.9212x1 - 2193.8838x2 + 2689.2405x3

Step-by-step explanation:

Given the data below:

Education (No. of years) Length of tenure in current employment (No. of years) Age (No. of years) Annual income ($) 17 8 40 124,000 12 12 41 30,000 20 9 44 193,000 14 4 42 88,000 12 1 19 27,000 14 9 28 43,000 12 8 43 96,000 18 10 37 110,000 16 12 36 88,000 11 7 39 36,000 16 14 36 81,000 12 4 22 38,000 16 17 45 140,000 13 7 42 11,000 11 6 18 21,000 20 4 40 151,000 19 7 35 124,000 16 12 38 48,000 12 2 19 26,000 10 6 44 124,000

The estimated multiple linear regression equation that can be used to predict the annual income using number of years school completed (Education), length of tenure in current employment, and age using an online multiple regression calculator is :

y = - 143481.1924 + 10011.9212x1 - 2193.8838x2 + 2689.2405x3

According to the general form of a multiple linear regression model:

-143481.1924 = intercept(c) ; where regression line crosses the origin

10011.9212x1 - 2193.8838x2 + 2689.2405x3 are weight coefficients of the three predictor variables ; x1, x2, and x3

y = predicted variable

Where the regression line crosses the origin 10011.92x₁ – 2193.88x₂ + 2689.24x₃ are weight coefficients of the three predictor variables x₁, x₂, and x₃. Then y is the predicted variable.

A Linear system is a system in which the degree of the variable in the equation is one. It may contain one, two, or more two variables.

A survey conducted by a research team was to investigate how the education level, tenure in current employment, and age are related to annual income.

A sample of 20 employees is selected.

The estimated multiple linear regression equation that can be used to predict the annual income using the number of years of school completed (Education), length of tenure in current employment, and age using an online multiple regression calculator will be

[tex]\rm y=-143481.19 + 10011.92x_1-2193.88x_2+2689.24x_3\\[/tex]

According to the general form of a multiple linear regression model will be

[tex]\rm -143481.19 = intercept (C)[/tex]

Where the regression line crosses the origin 10011.92x₁ – 2193.88x₂ + 2689.24x₃ are weight coefficients of the three predictor variables x₁, x₂, and x₃.

y = predicted variable.

The surface of the figure is the amount of space on the figure

The new surface area would be half of the original figure

The question is incomplete, so I will give a general explanation.

Assume the surface area of the original figure is A.

Then the area of the new figure would be:

A2 = A * k

Where k is the scale of dilation.

From the question, we have:

k = 1/2

So, the equation becomes

A2 = A * 1/2

This gives

A2 = 1/2A

The above means that the new surface area would be half of the original figure

x² + (a + b)x + ab = (x + a)(x + b)

The surface area of this figure will be 991 square feet.

The area of a plane region or plane field refers to the area of a shape or planar substance, whereas surface area refers to the area of an open surface or the boundary of a multi-object.

A complex solid made out of triangular and rectangular prisms. The triangular prism is centred on the top of the rectangular prism.

The surface area of the shape is given as,

SA = 2(19 x 11 + 11 x 9) + 19 x 9 + 10x 9 + 13 x 12 + 13 x 12

SA= 2(209) + 171 + 90 + 156 + 156

SA = 418 + 171 + 90 + 312

Answer:

(4, 14)

Step-by-step explanation:

We are given;

Graph of: y = ax² + c

That it contains point (2, 14)

Now,we want to find which point lies on the graph: y = a(x - 2)² + c.

Now, symbol "a" means the value of horizontal shift because the constants are grouped with x.

If the value of "a" is greater than 0,then it means that the graph shifted to the left by "a" units while if the value of "a" is less than 0,it means the graph shifted to the right by "a" units.

Now, from the 2 graph equations given, and from the principle of graph shifts, we can say that the first graph has shift by 2 units to the right because "a" equals -2.

What this implies is that every point on the graph y = ax² + c shifts by 2 units right.

Thus, the points that lie on the graph y = a(x - 2)² + c are: (x + 2, y)

Thus, points are: (2 + 2, 14) = (4, 14)

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

Four friends shared a pizza

Now , Felix 1/12

Lucy 1/4

Ned 1/3

An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax² + bx + c = 0, where x is the variable, a and b are the coefficients, and c is the constant term. The fact that the coefficient of x² is a non-zero term (a 0) is a necessary need for an equation to be a quadratic equation.

As per the given data:

f(x) = 9m² + 3m - 2

To find the x-intercept of this function:

The roots of f(x) will be the x-intercepts of the given function.

f(x) = 9m² + 3m - 2

9m² + 3m - 2 = 0

9m² - 3m + 6m - 2 = 0

3m(3m - 1) + 2(3m - 1) = 0

(3m + 2)(3m - 1) = 0

The roots are m = -(2/3) and m = (1/3)

Hence, the x-intercepts are -(2/3) and (1/3).
